Heterocyclic quaternary ammonium salts as phase transfer catalysts for aromatic ether imide preparation |
| abstract |
Heterocyclic quaternary ammonium salts such as N,N-di-n-butylpiperidinium bromide are excellent phase transfer agents for the preparation of aromatic ethers, as by the reaction of the disodium salt of bisphenol A with 4-nitro-N-methylphthalimide. |
